【Abstract】 CATIA was used in the piston’s solid modeling, then the model was imported into Patran, and the static analysis was made with the help of Nastran. The piston’s stress and deformation under mechanical load were achieved, and the dangerous stress region was also found out, which will provide a good theoretical basis for improving design.更多还原
